You only need to know the basics about these phases: If you install an adjustable charge controller you will have to set your float, bulk and absorption charging voltages. If you were using alkaline batteries, then throw them out. In a dry, dusty environment, they might need a monthly cleaning. Use your solar light instructions to help you disassemble your lights. Determine the state of charge or depth of discharge (DOD) by checking the specific gravity and voltage of the battery.

Most newly purchased solar lights come with rechargeable batteries. Conclusion. For this reason, take your solar light indoors to a nice clean area before opening it up. Most of what you need to know about flooded unsealed lead-acid batteries can be found above. If this is the case, you can get away with setting both phases at the same voltage. It looks like a bent in half piece of metal that comes in contact with the battery. Solar lighting has become a popular choice in updating walkways, landscaping, and any place an outdoor light is needed. When discharging, oxygen atoms from lead oxide (PbO2) in the positive plate react with hydrogen atoms from sulfuric acid (H2SO4) in the electrolyte. As you probably guess, these are going to produce water (H2O). Battery terminals need to be regularly cleaned with a mixture of baking soda and distilled water using a battery terminal cleaner brush. In fact, Saturn V rockets used hydrogen and oxygen as fuel in their upper stages. Wearing goggles while handling corroded batteries is also a good safety measure, just in case any residue splashes up. When you install a solar light, make sure the location of installation is a sunny place. The solar light is all cleaned up!

You could also run the panel under a faucet, but make sure to keep the water away from the light’s internal electronics. 4. Keep the spray can moving. Some systems also use fans to help vent the gasses out. Sulfation occurs when the battery has a low charge or electrolyte level.Due to the dangers of sulfation it is very important to monitor, maintain and control these two factors in flooded batteries. If there’s a lot of dirt on the inside, you can rinse it under a sink. Normally a solar light should get 4-5 hours daily direct sun light to effectively charge the batteries and shine brightly during night hours. This could scratch the panel.
